Cross border debt investment permissions: specified instruments, funding routes and remittance rules govern non resident purchases and proceeds. Schedule 1 sets out which debt instruments non residents may buy, the investor categories covered and the conditions for payment, sale and repatriation. FPIs may purchase specified instruments on a repatriation basis subject to SEBI/RBI terms and may offer permitted instruments as collateral for exchange traded derivatives. NRIs/OCIs have distinct repatriation and non repatriation entitlements for government securities, corporate bonds, mutual fund units and other instruments, with purchase funding and proceeds remittance required through prescribed accounts or inward remittances. Non resident central banks, IFSC securities account holders and rupee account holders have specified permissions under RBI/IFSC Authority conditions.
